When you draw a stroke and hold you get the curve - at the moment you can switch the sculpting tools like clay / mask / brush etc. but not to tube … tube is also a curve . So maybe it’s also possible to keep the curve when switching to tube / lathe…
Or maybe validate stroke but tube appears…. don’t know
It would be so nice if there was a option for this…
I didn’t know that. It sounds useful. And no relation with your request but may I ask you how to move this to the bottom like in image you posted?
It’s a 2.9 Beta feature not available for 2.8.
And I don’t know the release date 
…
Oh it’s my phone’s one. I have 2.9version in my desktop. I posted it with my phone since I was hassle.
Ah, you want view cube on bottom ? There is a setting in display settings - Top Menu scroll down…
Thank you so much
